' 1925. Serial iyto lmfifiq.

This invention relates to a tractor plow, which is driven preferably-by an "internal combustion engine, and provided with aplurality :of plows arranged in the form of a gang, so that it is'adapted to be used in conducting farm operations on a comparatively large scale.

The present application is a division of my earlierapplication, Serial No. 1,244, filed January 8, 1925.

The object of the invention herein claimed is .to-provide improved trash feeding means for disposing of the trash in front ofthe plows, so that it will be turned under, and specifically to provide positively, driven means which feeds the trash rearwardly atsomewhat greater speed thanthe forward movement of the plows. i

' The specific constructionand operation of the various elements constituting the subject matter of the present application will be more specifically described in connection with the accompanying drawings, which illustrate the samein their preferred form.

In the drawings:

Figure 1 is aYside'elevation of the invention, with parts broken away in order to show'more clearly the operative mechanism.

Figure 2 is a vertical section taken substantially on the line 22 of Figure l, and showing particularly the operation of' the colter disks and trashfeeders.

Figure 3 is a detail view, partly in section, showing the roller gear drive for the I shaft which carries the colter disks and trash feeders. v

Figure 4 isadetail view, partly insection, showing the roller gear drive for the tractor wheel.

Figure 5 is a detail View of one of the trash feeders with its shaft shown in section.

The tractor plow, to which the present .invention relates, includes a' main frame, having a central longitudinal member 1 which may be called the backbone of the machine, and is preferably tubular :and of comparatively large diameter, so as to secure the maximum rigidity to resist lateral .and torsional strains. Velded or otherwise secured to the rear end of said backbone is a horizontally disposed ring 72, which is supported by ,arear wheel 3. Siecuredto-the frontend of the backbone 1,, in similar manner, is a strong and rugged transverse beam 4, forming a substantial support for the engine block 7,

hare provided within the "engine block 7,

shown n Figure 2','and lined w1th bushings :The engine herein shown has .two'cylinders 1-6 and 17 securedto its front and rear ends respectively, and bear1ngsj18a'nd 19 20 and 21 respectively, for supporting a crankshaft 22 The latter is provided with .Thedrivingmechanism between the engine and the bull wheel includes a pinion 42, mounted on the crankshaft 22 outside of the engine block 7. The pinion 42'mesh'es with'an 'idler gear 43 mounted on'a stud 44, which is secured to the engine block. The idler 43 in turn drives a gear wheel 45, which issecured to one end 'ofa counter.-

shaft 46, journaled in suitable bearings 47 which are also secured to the engine 'block. The opposite end of the shaft 46 has a roller gear 48 secured thereto, which mesheswith an internal .gear 49 formed on the inside of the rim of the bull wheel 26. i I

The frame of the machine is adapted to support a plurality of plows 68, two being shown in the present instance. Each plow is secured :in the usual manner to a beam 69,

which is ,provided at its forward end with a gage wheel 70, and is pulled forwardly by means of a bar 71, pivotally connected to its front end The plows are, of course, arranged, so that one will follow the other. For supporting the plows at the required depth, the shoe of each "plow has secured thereto a rearwardly projecting arm 83, which is pivotally connected to the lower end of a support'ingstandard 84 mounted on the frame of the tractor.

As heretofore stated, .the'hub 25 of the bull Wheel is "journaled on the axle 24. The spokes 97, extending from this hub, are .curvedor dished, as shown in Figure 2, so as to clear the rollergear 48. The rim 98 is secured to the outerfends ofthe s pokes,.aa1d

sides or the engine block 7, the of these bars i through themedium of being pivotally supported on the outer surface of the bearing 19, and the other being pivota lly supported on an annular flange 102, which surrounds the axle 24tand overhangs the inner end of the hub 25. The lower ends of these hanger bars are provided with bearings 103, in which is journaled a yoke 104 having forwardly projecting arms 105. A shaft 106, journaled in these arms, carries colter disks 107 and trash feeder wheels 108. The shaft 106 at one end is provided with a roller gear 109, normally in mesh with the internal gear 49, and so pr0- portioned that the colter disks and trash feeders will be rotated slightly faster than the forward movement of the machine. The arms 105 have rods 110 pivoted,'as at111, to their outer ends, which rods are telescopical- 1y connected to sleeves 112, pivotally mounted at 113 on the hubs, of the hanger arms 101. Expansile coiled springs 11 l surround the-rods 110 and sleeves 112, and hold the gear 109 normally in mesh withthe internal gear 19, so as to positively rotate the shaft 106, and cause loose stalks and" other trash to be fed to the-colter disks 107 and to be severed thereby. The springs 114, however, are adapted to yield, so as to permit the roller gear 109 to be thrown out of mesh in case the trash feeders meet with any unusual obstruction.

In the normaloperation of the plow, the bull wheel 26' is driven from the engine the gears 12, L5 and 15, and the roller gear 48. The bull wheel, in turn, through the medium of the roller gear 109, which is normally in mesh with the internal gear 49, drives the shaft 106 at such speed that the lower portions of the colter disks 107 and trash feeders 108 more rearwardly slightly faster than the plows move forwardly. IVhatever trash is lying on the ground, herefore, is positively fed rearwardly into the path of the plows, and is cut or broken up, so that it will be turned under without clogging. The springs 114t are strong enough to hold the gear 109 al ways in mesh with the internal gear 49, except when such unusual obstruction is encountered by the trash feeders that a continued rotation thereof would be liable to cause breakage. In this event, the springs 11 1 will yield sufficiently to permit the roller gear 109 to slip.

While I have shown and described specifically the details of the trash feeding mechanism in what is regardedatpresent as its preferred form, it is to be understood that various modifications may be made therein without any material departure from the salient features of the invention as expressed in the claims.

What is claimed is: c

1. In. a tractor implement, the combinanesaeos tion of a wheel supported main frame, plows carried thereby, a transverse shaft journaled in front of the plows and having colter disks thereon, trash feeders on said shaft, and

means for positively rotating said shaft to feed the trash rearwardly as the traptorad- 'vances over the field.

2. Ina tractor implement, the combination of a main frame, whee-ls supporting said frame, one of said wheels being provided with an internal gear, an engine mounted on the frame and operatively connected with one of said wheels, plows carried by the frame, a transverse shaft journaled in front of the plows and having colter disks thereon, trash feeders also secured to said shaft, and a gearfo'nsaid shaft normally in mesh with said internal gear and driven thereby to feed the trash rearwardly as thetractor advances over the field' 3. In a tractor implement, the combination of a main frame, a plow carried thereby, a transverse shaft journaled in front of the plow and having a colter'disk thereon, trash feeders secured to said shaft and engaging the ground, and means for rotating said shaft in such a manner that the ground engaging port-ions of the trash feeders have a rearward movement with respect to the ground as the plow moves forwardly.

4. In a tractor implement, the combination ofa main frame, a plurality of wheels supporting said frame, including a traction wheel provided with an internal gear, plows carried by the frame, hanger bars suspended to swing about the axle of the traction wheel as an axis, a yoke pivotally mounted in the free ends of the hanger bars and having spaced arms, a shaft journaled in said arms having a gear wheel normally in mesh with said internal gear, colter disks and trash feeders secured to said means connected to the outer ends of the yoke arms permitting them to swing anddisengage said gear wheel from the internal gear whenever unusual resistance is encountered.

5. In a tractor implement, the combination of a wheel supported frame, an engine mounted on'the frame and operable to drive one of the supporting wheels to'move the tractor over the field, saidengine having a crank shaft in alinement with the axis of the driven wheel, hanger bars mounted to swing about said crank shaft as an axis, a shaft mounted in said hanger bars, colter disks and trash feeders secured to said last-mentioned shaft, and means to'drive the same from the driven ground wheel to feed the trash rearwardly.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature.
